Description
Technical field
The invention belongs to mini-tiller technical fields, specifically, more particularly to a kind of multi-purpose grass mower transmission case body structure.
Background technology
Grass trimmer is also known as weeder, grass mower, lawn mower etc..Grass trimmer be it is a kind of for cutting the grass on a lawn, vegetation etc.
Machine tool, it is made of cutterhead, engine, traveling wheel, walking mechanism, blade, handrail, control section.Cutterhead is mounted in
On traveling wheel, engine is housed on cutterhead, blade is housed on the output shaft of engine, blade is existed using the high speed rotation of engine
It is improved much in terms of speed, saves the activity duration of weeding worker, reduce a large amount of human resources.
Currently, in order to adapt to the needs of modern agriculture, corresponding equipment is mixed on grass trimmer can carry out farming, draw water, send out
The operations such as electricity, spray, spray, form multifunctional farm implements；Towed vehicle can also be drawn and carry out short-distance transport.Biography will certainly be changed in this way
The transmission system of system grass trimmer makes the power of engine not only be transmitted to shear driving mechanism, but also will be to other working rigs
Structure transmits, and how to design the transmission case to shear driving mechanism passing power, is technical problem urgently to be resolved hurrily in industry.
Invention content
In view of the drawbacks described above of the prior art, technical problem to be solved by the invention is to provide a kind of multi-purpose grass mower
Transmission case body structure.
Technical solution of the present invention is as follows：A kind of multi-purpose grass mower transmission case body structure has shell, it is characterised in that：Institute
The case structure that shell is upper end and front end opening is stated, is made of the side plate of bottom plate, backboard and the right and left, before the bottom plate is
It is high step-like after low, it is provided with axis hole in the high section of bottom plate, the scissors clutch rocker arm shaft of setting on one side of low section of rear end of bottom plate, this is cut
Knife clutch rocker arm shaft is perpendicular to low section of bottom plate, and the upper end of scissors clutch rocker arm shaft passes through low section of bottom plate, and the two is mutually welded solid
Fixed, the lower end of scissors clutch rocker arm shaft offers the aperture for penetrating through its opposite side, in the rear ramp of the scissors clutch rocker arm shaft
Backing pin is set, and backing pin is parallel and close to scissors clutch rocker arm shaft；
The front end of the side plate integrally extends forward, forms flange, is provided with mounting hole on the flange, and flange inner wall just
Nut is welded with to the position of mounting hole, the top of the side plate is higher than backboard, is equipped at the rear portion on side plate top opening up
The first bayonet, the front end at the top of side plate is equipped with opening the second bayonet facing forward, the middle part setting lock of plate face after the backboard
Only journal stirrup, is provided with lockhole on the locking journal stirrup, and the lock pin of lockhole described in face is arranged on two positioning lugs, the two positioning
Journal stirrup is located at locking journal stirrup on straight line, and the lock pin, which is located on the shank between two positioning lugs, sets positive stop lug boss,
The positive stop lug boss is cyclic structure, and the diameter of positive stop lug boss is more than aperture and the locking of locking journal stirrup of positioning lug locking pin hole
The aperture in hole.
Using above technical scheme, shell is the case structure of upper end and front end opening, and moulding is simple, system easy to process
Make, the opening of shell upper end is sealed by main transmission babinet, and the opening of housing forward end is sealed by scissors driving arm, is saved in this way
Shell materials, reduce material cost；Bottom plate is low early and high after step-like, and not only volume is more small and exquisite, occupies little space, and
It can avoid interfering with walking mechanism, in order to which scissors transmission case is arranged；Since shell and main transmission babinet and scissors drive
After dynamic holder engagement, there be gap in front thereon, needs to arrange that shield is sealed, mounting hole on side plate front end boss and
The second bayonet at the top of side plate keeps shield install convenient, connection on shell firm, by what is played the role of fastening for connecting shield
Nut is fixed on the inner wall of side plate flange in advance, can reduce the installation difficulty of shield, keeps shield assembly more convenient；Side plate top
The first bayonet be used to be clamped with main transmission babinet, play a part of to position, and the lifting lug of the main transmission bottom of box is just caught in lock
Only between journal stirrup and one of positioning lug, lock pin is moved towards the direction of locking journal stirrup, lock pin is made to pass through the mistake on lifting lug
Lockhole on hole and locking journal stirrup, you can realize the fixation of shell and main transmission babinet, operation is very simple and convenient, and lock pin is set
Positive stop lug boss is set, can prevent lock pin from falling off from two positioning lugs.Scissors clutch rocker arm shaft is opened for being set with clutch rocking arm
Aperture of the mouth pin on scissors clutch rocker arm shaft, limits clutch rocking arm, to prevent clutch rocking arm from falling off, but does not influence clutch
The flexibility that rocking arm is operated around scissors clutch rocker arm shaft；Backing pin limits the swing angle of clutch rocking arm, makes clutch rocking arm
It can reliably operate.
For the ease of selection, production cost is reduced as far as possible, it is ensured that has the enough structural strengths, the shell to be by thickness
2.5-3.0mm stainless steel plate be made.
Preferably, the high section of the bottom plate is mutually parallel with low section, by tilting section transition between high section and low section, and
Angle between high section and tilting section is obtuse angle.
It is fixed with washer in the bottom surface of the bottom plate high section, axis hole described in the centre bore face of the washer.Axis hole is for wearing
If the mandrel of drive pulley, which is locked by hex nut, and washer separates hex nut and bottom plate, avoids tightening hexagonal
Bottom plate is damaged when nut.
Preferably, the upper end of the backing pin is mutually fixed for low section with bottom plate, the lower end of backing pin is formed with convex annular
Platform.
Advantageous effect：The configuration of the present invention is simple, compact, compact, production cost is low, on the one hand can facilitate and main biography
Dynamic babinet connection, and can ensure that the fixing of connection, on the other hand, the assembly that can reduce shield and other periphery members is difficult
Degree, and closed space is formed by shield, main transmission babinet and scissors driving arm, keep machinery not exposed, true
While protecting internal operations partial reliability, safety is good.
